Tenant damages upon site visit

[Sean Kehoe]

Need some help. Have one property and things have been smooth for the most part. I am managing this site remotely as I now reside in SLC and just happened to be in town last week when the tenant called about a leaky backyard hose bib. Seeing as I was in town, and have fixed this in the past when I lived in the property, I cruised over and fixed it. 

Upon arrival I noticed excessive amounts of misc trash and personal belongs strewn throughout the front yard, creating an unsightly appearance and sprinkled amongst this trash I noticed that my new carpet that had been installed in the the bedrooms had been removed. I didnt bring it up at the time as I wanted to take pics and formally write up my issues for email, but was wondering what I can do there. I never received any communication that  it needed repair or there were issues so I assume their dogs destroyed it. 

Can I send a warning about the overall status of the property ( In the lease I have addendums about appearance and upkeep, lawn maintenance  and care, etc) along with the demand that all carpet is to be replaced on their dime and all color schemes to be approved by me before install, as well as install to be preformed by a professional with a warranty? Also, will email suffice or does this have to be certified mail?

They killed the yard as well and tenant claimed hes getting that replaced on his own but I want pics and professional install there as well. ( this was in the lease as well that the grass was to be maintained and kept alive and well).

Bad thing- These were friends and I dint do a damn move in checklist, but did get a post move out video which shows condition. I know, I know- rookie mistake that wont happen again.

Thoughts?!
